Abstract: A method for managing metadata in a scale out storage system is disclosed. The system includes a plurality of nodes, a storage pool, first metadata that maps logical addresses of logical data blocks to corresponding content identifiers, and second metadata that maps content identifiers to corresponding physical addresses of physical data blocks in the storage pool and maintains a reference count. During an add-a-node operation, the processors are configured to move from the existing nodes to the new node some of its physical data blocks, their content identifiers and reference counts in the second metadata without accessing or altering the first metadata. A method is disclosed to move a logical device from one node to another by de-activating the logical device's first metadata on the first node and activating and retrieving the logical device's first metadata on the second node.

Abstract: Systems and methods for predicting the outcome of a business entity are presented. In embodiments, a system may receive explicit data reporting or indicating activities of a business entity, and other data from which information regarding the activities or level of operations of the entity may be inferred. Using one or more data processors, the system may generate inferred data regarding the business entity from a selected portion of the other data, and use at least some of the explicit data and the inferred data to determine which one of a series of defined sequential active states of development the entity currently is in. The system may further, using the result of the determination as the current state of the business, predict a final stage of the business entity, and a probability of evolving to that final stage from the current state. Other embodiments may be disclosed or claimed.

Abstract: An image forming apparatus includes a first toner image forming unit, a second toner image forming unit, and a transfer section. The first toner image forming unit forms a first toner image with use of a first toner. The first toner has a complex viscosity that falls within a range from 625 Pascal-seconds to 3860 Pascal-seconds, both inclusive, at a temperature of 100 degrees centigrade. The second toner image forming unit forms a second toner image with use of a second toner. The transfer section transfers the first toner image onto a print medium, and transfers the second toner image onto the print medium in a region that overlaps a portion or all of a region where the first toner image has been transferred. The print medium includes a polymer compound.

Abstract: A system for detecting breach of merchant systems includes an extraction management system for extracting wildcard data from a dump site at which stolen account data is offered for sale. The system also includes an account breach identifying system for accessing stored transaction data from multiple banks and merging the extracted dump site data with the transaction data to create unique PAN (primary account number) data records (each set of wildcard data corresponds to only a single PAN) and multiple PAN data records (each set of wildcard data corresponds to multiple PANs). The unique and multiple PAN data records are stored and analyzed separately, and reduce the amount of data needed to identify a breached merchant.

Abstract: A method of computing a heart rate value compensates for noise derived from the subject, the sensor, the transmission, and/or other variables that can lead to false R-peak detection or missed R-peak detection. The method computes an updated heart rate based on a window of approximately ten seconds of digitized ECG readings broadcast from a sensor. A new value is calculated approximately every second such that the window of ECG readings overlaps considerably between consecutive calculations. The method compensates for noisy data by discarding heart rate samples that differ by more than a threshold amount from a previously calculated heart rate value. The threshold is adjusted based on a standard deviation of differences between heart rate samples. Prior to calculating a heart rate value, a forward-looking, pre-filter logic may be applied in situations where the raw data has an extremely low signal-to-noise ratio.
